Number of double-glazed windows. Important?

Choosing new windows, we are faced with a huge number of options. And managers who sell windows, especially if trying to confuse and roll in terms. Profiles, fittings, double glazing ... Unicameral, bicameral ... Go figure it out without training. Especially with the amount of glass. Does it matter the number of double-glazed windows? Let's find out. Our people are accustomed to call the word "glass" plastic window. In fact, it's not quite true. Actually windows - two (or more) of glass, hermetically connected with each other using remote frame made of aluminum. A hollow, perforated frame is filled with adsorbing powder - the so-called molecular sieve. Between the panes is pumped dry air, inert gas - or vice versa creates a vacuum. This design is not misted provides soundproofing and thermal insulation - is exactly why we appreciate the plastic window. Double-glazed windows are single-and two-chamber. In theory, cells may be more - but in practice even the three-compartment windows are relatively rare. Plastic box with mono-glazing is now considered a basic option. Such windows are well protected from external noise, keeping warm, transmits more light. Plastic box with mono-glazing reduces noise by 25 dB, and almost 20% increase thermal insulation compared to conventional windows. A lower price, compared to the windows with triple-pane windows, makes to think about. Indeed, the number of double-glazed windows can not matter? After all, put the same in Europe plastic box with mono-glazed windows - and nothing to live. Unfortunately, Ukraine is not the south of Europe. If the average temperature in January VNA yugeokolo five, in our country is at below. A window with a triple-pane windows keep the heat up to 30% better than mono-glazed windows .. As for the noise - and then a twin-glass it is not enough. If you live in the center for normal sleep your windows should be cut off of 40-45 dB. And this is only possible with plastic windows with triple-pane windows. And maybe if not a trifle, and immediately order the plastic box with three-chamber window panes? You can, of course. But note that even triple-pane windows, providing optimum sound and heat insulation, passed on the street only 69% of the world. And threechamber glass this ratio is even lower. Winter in our latitude is already short light day - whether to further reduce the amount of natural light? Of course, if your home is worth in a forested area, the problem of noise for you is not too relevant. The inhabitants of the Stalinist buildings with a thick wall, which even in winter, always keep vents wide open, perhaps, too, is to prefer plastic box with mono-glazing. For all other ideal is still triple-pane windows. After all, what we want, buying new windows? First of all - the heat and silence.
